Second.- Object of the Agreement

By virtue of this Agreement, the LESSOR leases to the LESSEE, who accepts, a Property described in the They State section I, which the LESSEE states that it knows and accepts, accepts, in its current
physical, building, legal, administrative, development and land registry status.

The LESSEE acknowledges that it receives the Property and
its installations and services in good conditions of use and in a good state of repair.

The LESSEE will use the Property mainly for the
specific activities of its corporate purpose, and particularly for the installation, operation and maintenance of data processing centres (DPC). It may also use the Property for complementary uses to the core activity provided that any such use does
not involve a greater percentage than that of the core activity and that the clients to whom any such services are rendered are also clients of the LESSEEs core activity.

As it is not a question of covering a permanent housing need of the LESSEE and the other people stated in Article 7 of the Ley de Arrendamientos Urbanos [Law of Urban Leasings], this agreement is excluded
from the system of protection established in titles I and II of the aforementioned Law, and is governed, pursuant to Article 4 of aforementioned Law, by the provisions of this Agreement, by the provisions of Title III of the aforementioned Law, in
terms of the Articles whose application has not been expressly excluded in the conditions of this document or do not contradict the provisions of this Agreement, and subsidarily, by the provisions of the Civil Code.

Third.- Term of the Agreement

3.1. The Leasing Agreement will take effect as of its signature, on October 10, 2011 (the Start Date), and will have an
Obligatory Compliance Period offifteen (15) years as of the aforementioned date of October 10, 2011, until October 9, 2026.

3.2. Following the expiration of the Agreement because the Obligatory Compliance Period of fifteen (15) years has elapsed, this Agreement will be automatically discharged.

3.3. If for any reason the LESSEE decided to abandon this Agreement or vacate or were obliged to vacate the Property before the fifteen
(15) years of Obligatory Compliance have elapsed, it must pay the LESSOR the amount equivalent to the rent that would remain until the fifteenth year, taking into account, for the aforementioned calculation, that the updated rent for
each annual period will be that which results from the application of the increases agreed to in this Agreement, until the end of the term of fifteen years, by way of damages which such an early discharge causes the LESSOR.



---

The indemnities provided for in this agreement will be added to the amount resulting from the provisions of
the previous paragraph if the Work established in this Agreement has not been completed pursuant the Work Execution Project and to the corresponding administrative licence, without prejudice to other indemnities and amounts established in this
Agreement in the event of non-fulfilment.

Fifth.- Economic Conditions

which is the object of this agreement will consist of:

For the first annual leasing period, from October 10, 2011 until October 9,
2012, the amount of * * *.

As of the third annual leasing period, i.e. from October 10, 2013 and thereafter, the amount of * * *, to be
revised annually pursuant to the provisions of clause 5.6 of this agreement.

The aforementioned amounts refer exclusively to the price of the
leasing and do not include taxes or expenses.

5.2. Value Added Tax (VAT) and/or other Taxes

This leasing is subject to Value Added Tax (VAT) and/or to any tax that may be levied on the leasing throughout the term of this Agreement, and
consequently the total amount of each one of the successive rental invoices must accrue, according to the legal rate applicable at all times, and automatically, the corresponding amount of the aforementioned tax, which will be stated separately from
the rest of the items on the corresponding invoice.

5.3. Payment of the Rent

Payment of the rent and other concepts which in accordance with the Law and the clauses of this Agreement may be charged to or paid by the LESSEE, will be made by means of bank transfer to CHAINCO
INVESTMENTS COMPANY, S.L. into the Caixabank no. account 2100-2138-15-0200438756, which to this end is indicated in this act by the LESSOR.

The rent will be paid by the LESSEE to the LESSOR in twelve monthly payments, paid one month in advance, within the first FIVE (5) days of each month, plus the corresponding VAT.



---

The LESSOR will be obliged to issue, on a monthly basis, to the LESSEE, the corresponding invoices for the
amounts resulting from the provisions of this clause. In no case will failure to deliver an invoice constitute an excuse for non-payment of the rent by the LESSEE.

In this act, the LESSEE delivers to the LESSOR, as the first rent from the Start Date of this Leasing Agreement until October 31, 2011, the amount of * * *, by means of the nominal promissory note
no. 6.075.722-0 8201-4 of the CaixaBank bank. The LESSOR receives the aforementioned cheque subject to it being credited to the account, granting, in this act, the firmest and most efficient letter of payment for the aforementioned amount.

5.4. Exemption from withholding of the LESSEE

This agreement will be subject to withholding in each payment of the monthly rent agreed to according to the applicable legislation. Nevertheless, when the law envisages exemption from making the
withholding, the LESSEE will make no withholding if the corresponding legislative requirements are met. When the withholding exemption requires a certificate that should be sent by the LESSOR to the LESSEE, the latter will make no withholding as of
the moment the aforementioned certificate is made available to it. The LESSEE delivers to the LESSOR in this act, attaching it to this contract, copy of the certificate issued by the Tax Authorities Exempting Lessors from making the Withholding.

5.5. Delay and non-payment of the Rent

Any delay in the payment of the rent will lead to a surcharge on the interests payable by the LESSOR at a variable annual rate that will be the result of applying, the interest rate on the Interbank
market published by the Bank of Spain at the time of the non-fulfilment of the payment plus a ten percent (10%) increase during the first thirty days, and twenty percent (20%) as of day 31 of the non-payment and until total payment of the
proper rent owing, besides all other expenses produced, without prejudice to the LESSOR being entitled to instigate eviction procedure due to lack of payment as of day sixty-one (61) as of the first day of the month of non-payment of the rent.

Non-fulfilment by the LESSEE of the obligation to pay the rent in the time, place and form established in this Agreement will entitle the
LESSOR to demand termination of this leasing agreement and commence eviction proceedings as provided for by this Agreement.

5.6. Update of
the Rent

5.6.1. The rent agreed to in clause 5.1 above will be updated as of the beginning of the fourth year (October 10, 2014) of
accrual of the leasing on the date of the end of each year of the term, and throughout the term of the agreement in accordance with the percentage variation in the consumer price index (hereinafter, the CPI), in the twelve (12) months
before the update in accordance with the data published for this purpose by the National Institute of Statistics (INE) or any organisation that replaces it, without, in any case, the increase in the rent being lower than three per cent
(3%) a year.

To this end, and for the provisions of the following points referenced to the CPI, the initial index taken for the revision
will be the index published by the INE on the effective date of the period being revised, and the final index taken will be the last one published before the expiration of the period being revised, and so on for each annual review.

If at the time of the update the aforementioned definitive indexes had not been published, the provisional index established by the INE will be applied,
and once the definitive index is known, the corresponding settlement will be made taking into account the date the new rent became applicable, and the corresponding balance will be paid to the LESSOR or LESSEE.

5.6.2. Without prejudice to the agreement made for the annual update of the rent in accordance with the evolution of the CPI, the parties agree to
exclude the application of the aforementioned update in the calendar years corresponding to the (6) sixth and (11) eleventh years, when, instead of the annual rate in force being updated according to the CPI, a percentage increase of
(6%) six per cent will be applied.

5.6.3. The variations in the rent derived from the revision agreed to in this clause
will be added to the rent of this Agreement and will therefore be part of the basis for successive revisions which will be carried out pursuant to the provisions of this clause.

as specifically provided for to this end, with all the effects established in this Agreement.

17.2. Failure by the LESSEE to pay the
